I have one more question. We have only ten minutes left. I wish to follow on from the discussion about ADHD. This is probably more from a therapeutic point of view, but are children who have ADHD more inclined, when they get into their teenage years, to pick up substances? I am talking about the link between ADHD and - I will not even use the word "addiction" - let us just say substance misuse or alcohol misuse. Is there a strong link in that regard?
